NUT LOCK.

SPECIFICATION forming part of Letters Patent No. 680,690, dated August 20, 1901. Application filed January 17, 1901. Serial No. 48,618. (No model.)

To aZZ whom it may concern:

Be it known that I, JOHN WILLIAM BRAN- -N ON, a citizen of the United States, residing at Marquand, in the county of Muskingum and State of Ohio, have invented certain new and useful Improvements in Nut-Locks; and I do declare the following to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to nut-locks.

The object of the invention is to providea lock of this character which shall be of such construction that all of the nuts used in connecting the fish-plates together at the meeting ends of rails may be simultaneously and securely locked.

With this and other minor objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, which will be hereinafter more fully described, and particularly pointed out in the appended claim.

In the accompanying drawings, Figure 1 is a perspective view of two rails, illustrating the application of my invention. Fig. 2 is a vertical cross-sectional view.

Referring now more particularly to the drawings, 1 denotes the meeting ends of two rails; 2, the fish-plates; 3, the bolts, and 4: the nuts. These parts are of Well-known con struction.

5 denotes a locking-bar provided with apertures 6, the walls of which are adapted to embrace the nuts and prevent them from turning.

7 denotes a tie-rod having one end attached to the bar at 8, thence bent downwardly to snugly fit one side of the base of the rail, and thence under the base and having its extremity extending upward along the edge of the opposite side of the base. To this upwardlyextending end is pivoted a cam-lever 9, which is adapted to act against the edge of the base of the rail and draw the parts firmly together to hold them in locked position.

From the foregoing description, taken in connection with the accompanying drawings,- the construction, operation, and advantages of my improved nut-lock will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and minor details of construction may be made Within the scope of the invention. without departing from the spirit or sacrificing any of the advantages thereof.

The device is an exceedingly simple one and may be applied to rails now in use with out changing the nuts or bolts that secure the fish-plates to the rails and the rails to each other.

Having thus described myinvention, what I claim, and desire to secure by Letters Patent, is

A nut-lock comprising a bar adapted to engage and prevent the rotation of the nuts of a railroad-rail, a tie-rod having one end con nected to said bar and adapted to engage and project under the base of the rail and having its other end provided with an upward extension, and a cam pivoted to said upper extension and adapted to engage the edge of the rail, substantially as set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

JOHN WILLIAM BRANNON.
